The boss ____ department Ms King worked ten years ago look down upon women

這裏選C其實是The boss of the department in which Ms. King worked ten years ago,主句的主語是The boss,而department是屬於The boss的，所有關系，所以要用whose,不用which。而之所以要用in是因為work當工作講是vi，要加介詞才能帶賓語。如果要選A的話，句子要改為:The boss of the department in which Ms King worked ten years ago…

整個句子的意思為：Ms. King 十年前工作的部門（公司）的老板瞧不起或者歧視女性。照這句話的意思看，樓主的句子look少了個"s",主語為第三人稱單數，壹般現在時，應為"looks'.
